TIE AND TIE-PLATE SUPPORT.

To all whom it may concern:

Be it known that we, CLEMENS W. AoKnn- MANN and FRANK B. ACKERMANN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Tie and Tie-Plate Supports, of which the following is a specification.

This invention relates to means for securing a rail to a tie by means of a tie plate, and is an alternative construction of the device of our application of the same title, Serial Number 762,419, filed April 19, 1913, which in certain cases may be used to advantage in place thereof.

The object of the invention is to secure the rail to the tie in such a way that the rail cannot get loose and move, thereby possibly injuring passengers on the trains passing over the rail, and also so that the tie plate cannot move thereby cutting or chewing into the tie as has been common in prior constructions.

The special object of this invention is to so secure the tie plate to the tie that only one central fastening device is required thereby reducing the number of holes which have to be made in the tie, consequently reducing its liability to deterioration, the rail itself being securely fastened to the tie plate instead of through the tie plate to the tie.

The invention consists in a device capable of carrying out the foregoing objects, which can be easily and cheaply made and installed, which is satisfactory in operation and not readily liable to get out of order.

More particularly, the invention consists in special means for securing the tie plate directly to a foundation member secured in the tie itself.

It also consists in other specific details which will be hereafter more fully described and claimed.

Referring to the drawings in which similar numerals indicate the same parts throughout the several views, Figure 1 is a sectional end view of a rail and a side view of a tie showing the device of this invention in its preferred form applied thereto. Fig. 2 is a plan view taken immediately under the rail showing the central portion of the top of the tie plate and the securing screw in the center thereof.

Referring to Fig. 1, the rail 50 of any ordinary form rests upon a tie plate 52, preferably of metal, which in turn is located over a screw threaded metallic foundation Specification of Letters Patent.

member 54 inserted in the tie 56. The foundation member 54 is hollow and has at its lower portion lugs 58 adapted to be engaged by a wrench for screwing the foundation member into the tie. The opening in the foundation member above these lugs is provided with internal screw threads 60 correspondingly engaging screw threads upon a central locking screw or removable lug (52 which passes through a corresponding opening in the center of the tie plate 52. This screw has all the functions of the rigid lug of the tie plate of said prior application in addition to those here ascribed to it. The head 64 on the locking screw 62 rests in a recess 66 provided for its reception. The top of the head 64- of the screw (32 is, when the parts are in normal position, flush with the bottom of the rail 50 and with the top of the tie plate 52, as shown in Fig. 1. In the center of the top of the screw 62 is a noncircular recess 68 adapted to receive a wrench for rotating the screw (32 along the screw threads 60. It will be noted that when the parts are assembled in the position shown in Fig. 1, the foundation member 55 i is securely fastened in the tie and that the screw 62 holds the tie plate 52 in contact with both the foundation member and the tie. As the screw threads 70 on the outside of the foundation member 54 are of large coarse pitch they very securely hold the foundation member in the tie, and the screw threads 60 being metallic the screw 62 is very securely held to the foundation member, the net result being that the tie plate 52 is more securely held to the tie than where ordinary wood screws or spikes through the tie plate into the tie are used.

The rail 50 is secured to the tie plate by the use of two or more short screws 79. which enter the tie plate but preferably do not pass through it into the tie, the heads 74 of these screws bearing against both the rail flange 76 and lugs 78 provided on the top of the tie plate, these and intervening lugs, fully shown, described and claimed in said prior application, being so arranged as to prevent sidewise movement of the rail across the tie plate. As the screws 72 do not enter the tie 56 the tie is not thereby weakened or rendered subject to decay germs which enter along the walls of any object inserted in a wooden block such as a tie.

The friction of the tie plate 52 on the top of the tie and the top of the foundation member 54: is ordinarily sufficient so that no rotation of the tie plate with reference to the tie can take place, but even where this is possible it is prevented by the engagement of the screws 72 and the flanges on the tie plate with the flanges of the rail.

Comparing this form of the device with that of our prior application, it will be noticed that the general external outline of the rail, the tie and the foundation member and the tie plate are the same, but that instead of the tie plate being provided with a rigid lug which fits into the recess in the foundation member without being screw threaded therein, a removable lug or screw 62 is used to secure the tie plate to the foundation member and thus to the tie with the result that the screws 7 2 can be made short as shown so that they do not enter the tie thereby more or less sooner or later weakening it.

Having thus described our invention, what we claim as new and desire to secure by Let-- ters Patent, is:

1. In a device of the class described, the combination of a tie, a rail to be attached thereto, a foundation member screw threaded into the tie, a tie plate under the rail and over the foundation member, detachable means for securing the tie plate to the foundation member, and means for securing the rail to the tie plate.

2. In a device of the class described, the combination of a tie, a rail to be attached thereto, a foundation member screw threaded into the tie, a tie plate under the rail and over the foundation member, screw means for securing the tie plate to the foundation member, and means for securing the rail to the tie plate.

8. In a device of the class described, the combination of a tie, a metallic foundation member inserted in the tie, a tie plate over the tie and foundation member, detachable means for securing the tie plate to the foundation member, arail resting upon the tie plate and means for securing the rail to the tie plate independently of the tie.

4:. In a device of the class described, the combination of a tie, ametallic foundation member inserted in the tie, a tie plate over the tie and foundation member, screw threaded means for securing the tie plate to the foundation member, a rail resting upon the tie plate, and means for securing the rail to the tie plate independently of the tie.

5. In a device of the class described, in combination with a tie, a metallic foundation member screw threaded into the tie, a tie plate over the tie and foundation member, a screw securing the tie plate to the foundation member, a rail and means independent of the tie for securing the rail to the tie plate.

6. In a device of the class described, the combination of a rail, a tie, a metallic foundation member screw threaded into the tie with its central axis in approximately the central plane of the rail, a tie plate below the rail and over the tie and foundation member, a screw lug in screw threaded engagement with the foundation member having a head adapted to enter and lie in a recess counter-sunk in the top of the tie plate, and means for securing the rail to the tie plate.

7. In a device of the class described, in combination with a tie and a rail to be secured thereto, a foundation member screw threaded into the tie, a tie plate over the tie and foundation member, a headed screw through the tie plate engaging the foundation member, the head of said screw normally resting in a recess provided for it in the tie plate, a tie resting upon the tie plate and covering said screw, flanges on the outer edges of the tie plate, screws through the tie plate but not entering the tie, and heads upon the screws engaging the flanges of the rail and the flanges of the tie plate, all of the parts being shaped, arranged and disposed substantially as shown and described for the purposes set forth.

In witness whereof we have hereunto subscribed our names in the presence of two witnesses.
